Campanula plant named ‘10.00.99’

ABSTRACT

A distinct cultivar of Campanula plant named ‘10.00.99’, characterized by its upright and outwardly spreading growth habit; single violet blue campanulate flowers; and temperature tolerant from −15 to 35° C.

Botanical classification/cultivar designation: Campanula×haylodgensis cultivar 10.00.99.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Campanula plant, botanically known as Campanula×haylodgensis, and hereinafter referred to by the name ‘10.00.99’.

The new Campanula is a naturally-occurring branch mutation of an unidentified selection of Campanula×haylodgensis, not patented. The cultivar 10.00.99 was discovered and selected by the Inventor from within a population of plants of the unidentified selection of Campanula×haylodgensis in a controlled environment in March, 2000, in Odense, Denmark.

Asexual reproduction of the new cultivar by cuttings taken at Odense, Denmark, since March, 2000, has shown that the unique features of this new Campanula are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar 10.00.99 have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and/or light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘10.00.99’. These characteristics in combination distinguish ‘10.00.99’ as a new and distinct cultivar:

1. Upright and outwardly spreading growth habit.

2. Single violet blue campanulate flowers.

3. Temperature tolerant from −15 to 35° C.

Plants of the new Campanula are most similar to plants of the parent, the unidentified selection of Campanula×haylodgensis. Plants of the new Campanula differ from plants of the parent selection in the following characteristics:

1. Plants of the new Campanula were more freely flowering than plants of the parent selection.

2. Plants of the new Campanula had single flowers whereas plants of the parent selection had double flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ from the color values cited in the detailed botanical description which accurately describe the colors of the new Campanula.

The photograph on the first sheet comprises a side perspective view of a typical plant of ‘10.00.99’.

The photograph on the second sheet comprises a close-up view of typical flowering stems of ‘10.00.99’.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used. Plants used for the above-mentioned photographs and botanical description were grown in Odense, Denmark in 6-cm containers in a glass-covered greenhouse. During the production of the plants, day temperatures were about 18 to 20° C., night temperatures were about 16 to 18° C., and light levels were about 25 W/m². Plants used were about 12 weeks old when the photographs and description were taken.
